4-peak polyurethane ceiling panel PR-4T 39/333

Technical Specifications:

Insulation of Polyurethane Panels:

The PUR (polyurethane) foam is chemically neutral, non-toxic, and produced using environmentally friendly technology with pentane (CFC and HCFC free). Domolam panels are produced with PUR foam classified as reaction to fire Cs3d0 or, alternatively, with High Index PIR (polyisocyanurate) foam, classified as Bs1d0, in accordance with EN 13501-1, EN 11925-2, and EN 13823 standards. Wall panels (vertical installation – EN 1364-1) have a fire resistance rating of EI 30: E60, and roof panels (horizontal installation – EN 1365-2) have a rating of REI 30: RE60 for 100mm thickness, according to EN 13501-2.

Both PUR and PIR High Index foams contain over 95% closed cells, providing resistance to moisture absorption and excellent bonding with the metal facings.

Advantages of the oikiskos roof panels:

1. Innovative connections ensure excellent waterproofing and airtightness.

2. They feature special reinforcing shapes on the sides of the trapezoids for increased load resistance.

3. Depending on their type, they can be combined with pioneering photovoltaic elements in the form of adhesive membranes.

4. They are produced with an innovative overlapping design along their length.

Notes:

Minor wool traces at the joints, small wool gaps, or slight absence of wool sealant along the side do not constitute quality issues, provided the functional integrity of the panel remains unaffected.

Roof panels are used for external roofs, designed to meet various construction needs with high aesthetic value.

Unloading:
Bundles of long panels should be unloaded using slings or long straps. Pre-painted sheets should not be dragged against each other.

Storage:
Panels must be placed at a minimum 5% incline and covered in a way that allows ventilation, to prevent vapor condensation and electrochemical corrosion.

Installation:
After completion of installation, any protective film (if present) must be removed, and surfaces should be cleaned of cutting/drilling debris.
It is recommended to use at least two fasteners per sheet and batten. Screwing should stop as soon as the metal surface begins to deform, to maintain both aesthetic and structural performance.
